BRICK-MOLDING MACHINE Specification of Letters Patent.

Patented July '7, 1908.

To all whom it may concern:

Be it known that I, HEZEKIAII S. BOWLER, a citizen of the United States, residing at Gloversville, in the county of Fulton and State of New York, have invented a new and useful Brick-Wielding Machine, of which the following is a specification.

This invention relates to means for forming bricks.

The principal object is to provide a novel and simple structure, whereby a comparatively great number of bricks may be molded at each operation of the machine, said machine being rapid in its operation and eliminating the necessity of'the slow tamping process now ordinarily employed in mechanisms of this character.

While the invention may either be ower or manually operated, a machine of the atter type is disclosed in the accompanying drawings, wherein:-

Figure 1 is a side elevation of such machine. Fig. 2 is an end elevation of the same. Fig. 3 is a vertical sectional view therethrough, and Fig. 4 is an end elevation, showing the relation of the parts when the mold body is elevated.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a suitable bed 5 is employed, having spaced upright guide standards 6 mounted thereon. The upper ends of these guide standards are connected to a cross head 7. Slidably mounted on the standards is a mold body 8, said body having collars 9 at its corners, through which the standards 6 pass. The mold body 8 is provided with a plurality of brick-shaping compartments 10, having open tops and bettoms, and of greater depth than the thickness of the completed bricks. This is an important feature, as hereinafter explained. The mold body is arranged to normally rest upon removable pallets, one of which is shown at 11, said pallets being placed upon the bed 5, between the standards, and con stituting closures for the lower ends of the compartments 10. A plunger cooperates with the mold body, and comprises a plate 12, having collars 13 at its corners, which collars are slidably mounted on the stand ards 6. The plate is rovided with a plurality of spaced depent ing heads 14 that are arranged to enter the different compartments 10, as will be clear by reference to Fig. 3.

While any suitable mechanism may be employed for operating the above described parts, in case the machine is to be manually operated, the following actuating means is preferably employed. A screw stem 15 is carried by the plunger, and passes through the cross head 7. A hand wheel 16, located below said cross head, has a hub 17, journaled therein, and surrounding the stem, having a threaded engagement with the same and retained by a collar 18 in the cross head. It will thus be evident that by rotatin the wheel 16 in one direction, the plunger .wiTl be moved downwardly into the mold body, and by rotating it in the opposite direction, said plunger will be elevated. A

rock shaft 19, journaled in suitable cars 20,

carried by the cross head 7, is provided with crank arms 21, and links 22, connected at their upper ends to the crank arms, are pivotally connected at their lower ends to cars 23, secured to the ends of the mold body. One end of the rock shaft 19 is rovided with another crank arm 24, and a Eink 25, connected to the crank arm 24, has a connection with another crank arm 26, secured to an actuating lever 27, fulcrumed, as shown at 28 on one end of the bed 11. Thus upon the siwnging movement of the lever 27, theshaft 19 will be rocked, and the mold body raised or lowered.

In using the machine, the plunger is ele vated, the pallet 11 is placed u on the bed, and the mold body is arranger thereupon. The compartments are then filled with the material and leveled off even with the top of the body, after which the plunger is lowered, and the material pressed to the desired thickness of the bricks. Then the lever 27 is operated to rock the shaft 19, and this causes the elevation of the body, the plunger heads 14, however, holding the bricks upon the pallet, as shown in Fig. 4. After the mold body has been raised clear of said bricks, the plunger is again elevated, leaving the molded articles on the pallet, which may be removed and replacedbya new one, whereupon the o eration is repeated. It will be seen that t 1e structure disclosed is an exceedingly simple one, and that a comparatively great number of bricks may be simultaneously formed. Moreover, there is no tamping necessary, the mold body compartments being of a sufficient depth to receive at first the entire amount of material necessary to form the completed bricks.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the s irit or sacrificing any of the advantages ofthe invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a brick molding machine, the combination' with a bed, of spaced upstanding guide standards mounted on the bed, a cross head connecting the upper ends of the standards, a removable pallet that rests on the bed between the standards, a mold body slidably mounted on the standards and having a plurality 'of brick-shaping compartments of greater depth than the thickness of the finished bricks, a rock shaft 1' ournaled on the upper ends of the standards, crank connections between the rock shaft and moldbody for mov ing the same towards and from the pallet, means for operating the rock shaft, a plunger slidably mounted on the standards and having depending heads that operate in the compartments of the body to ress the material therein to the thicknesso' the finished brick, a stem carried by the plunger and passing through the cross head, and an actuating wheel ournaled in said cross head and surrounding the stern, said wheel having a threaded engagement with the stem.

In testimony, that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
